More than half of voters in Arizona's Democratic primary say Kennedy's endorsement of Obama was important – and those holding this view voted for Obama by a wide margin.

Exit polls also suggest the Kennedy endorsement might have been influential among the state's Latino voters, who supported Clinton but by a smaller margin than in other states.

As elsewhere, white men supported Obama over Clinton by a small margin; white women voted for Clinton over Obama by a much larger margin. Latino women likewise voted for Clinton over Obama by a large margin, while Latino men were more evenly divided in their vote.
